Description

The present invention relates to a dispersible powder and a cosmetic containing the dispersible powder.

Conventionally, improvement of dispersibility of powder and application when blended in a composition have been studied.

For example, it has been studied to improve the dispersibility in aqueous media and oils by surface treatment of powder. Patent Document 1 describes that the dispersibility in silicone oil is improved by treating the silsesquioxane particles with silicone, but does not describe the dispersion in an aqueous medium. Further, the effect and usefulness when blended in a composition, particularly a cosmetic composition, are not described.

Further, Patent Document 2 describes a method of hydrophilically treating the pigment surface with a silane compound having a polyoxyalkylene group, but the surface hydrophilicity becomes too high, so that the powder agglomerates or is blended in cosmetics. If this is the case, there is a problem that the feel at the time of application is deteriorated.

Further, Patent Documents 3 and 4 describe water-based makeup cosmetics containing a high HLB surfactant and powder, which are mixed in a cosmetic composition to form a cosmetic. Since the method cannot suppress the agglomeration of powders, there are problems such as spread during application and poor spread. Further, Patent Document 5 discloses a powder in which a phosphorylcholine group is introduced on the surface of the powder. However, although this powder has dispersibility in water, the surface becomes too hydrophilic, so that it aggregates and deteriorates stability over time, absorbs moisture in the air, and makes the feeling of use heavy. There was a problem.

<Examples 11 and 12, Comparative Examples 7 to 9>
The dispersions shown in Table 1 were prepared and their dispersibility was evaluated.

[Evaluation methods]
The powder is dispersed in water and ethanol according to the formulation shown in Table 1 below, and is allowed to stand and stored in a constant temperature bath set to temperature conditions of 25 ° C, 50 ° C, and −5 ° C. Immediately after, take out at the timing of one week later, and let stand in a constant temperature bath at 25 ° C. for 2 hours. Then, 10 times of shaking with the stored sample bottle was set as one set, and the presence or absence of powder agglomeration was visually evaluated at each end of the set.

[Evaluation criteria]
◯: Dispersion in 1 to 2 sets ×: Dispersion in 3 or more sets

※不可：作製の時点で分散していない。
各成分の配合は合計が１００となるように調整した。

* Impossible: Not dispersed at the time of production.
The composition of each component was adjusted so that the total was 100.

As shown in Table 1, it was confirmed that Examples 11 and 12 using the dispersible powder of the present invention had excellent dispersibility and high dispersion stability. Comparative Example 8 cannot be produced, and Comparative Example 9 disperses immediately after production, but sedimentation and agglutination occur over time, making it difficult to disperse. Further, even if the surface treatment is performed only with the nonionic surfactant as in Comparative Example 7, the dispersibility is not improved. From the above, it can be seen that surface treatment with a (meth) acrylic (co) polymer containing a repeating unit having a phosphorylcholine group as in the present invention has high dispersion stability.

<Examples 13 to 18, Comparative Examples 10 to 16>
The lotions shown in Table 2 were produced by a conventional method, and their usability was evaluated.

[Sensory evaluation method]
About 5 g of the lotion obtained by the formulation shown in Table 2 below was applied to the skin, and the spread, uniformity, and spread during application were sensory-evaluated. The spread at the time of application indicates the feel and comfort of the application such as slipperiness (lightness) and smoothness at the time of application, and the spread indicates the length and area physically extended. Regarding the dispersion stability, the presence or absence of powder agglomeration was visually evaluated in the appearance of the product one week after production. The results are shown by the following evaluation criteria according to the number of panelists who answered "effective".

[Evaluation criteria]
⊚: 4 to 5 responded that it was effective ○: 3 responded that it was effective △: 2 responded that it was effective ×: 1 or 0 responded that it was effective

各成分の配合は合計が１００となるように調整した。

The composition of each component was adjusted so that the total was 100.

As shown in Table 2, the lotions of Examples 13 to 18 using the dispersible powder of the present invention have very excellent dispersibility, high dispersion stability, a uniform cosmetic film, and at the time of application. It was confirmed that the spread was good and the spread was good.

On the other hand, in Comparative Examples 10 to 16, the powders obtained in Comparative Examples 1 to 6 were used, but the dispersion stability, spread during coating, uniformity, and spread were inferior. From the above, the dispersible powder of the present invention has excellent dispersibility and high dispersion stability, and when blended in cosmetics, the cosmetic film is uniform, spreads at the time of application, spreads well, and has a feeling of use.
